Questions About Carrotwood Trees

I couldn't find anything in my research to suggest that the carrotwood tree was allelopathic, so let's talk about your mango tree and see what is happening with that. How old is the tree? How is your mango tree not thriving? How have you cared for it in terms of watering and fertilizing? Is it getting full sun? How long ago was the carrot wood tree removed before the mango tree was put in its place? And how was the carrotwood tree removed - any chemicals?

I have a carrotwood tree that I’m having a hard time growing grass under. People have told me the tree kills the grass. I live in southern Florida on the west coast. Is there any type of grass I can grow under this tree?? I’m thinking on planting St. Augustine. Thank You; John

The carrotwood's roots seem to be very hungry and grass and other plants have a hard time competing with them (the roots can also ruin sidewalks nearby), so removing it is probably the best option. Some say that the seed pods or the seeds of carrotwood also kill the grass. If you keep the tree, try to remove all the seedpods that fall. The seeds will also grow readily into carrotwood seedlings. I am not sure of any specific types of grass that would tolerate the tree better.
